' tion. Q

(hir invention relates th a. 'new and useful improvement. inaniilriction or roller been ingy hubs, and has` l'or vits object theoonstrnclion ol' :i solid hub in which are placed rolls which revolve onspindles or journals upon :in axle olA two diameters, or straight, as'best suits the requirements of different type ulieels, therebyconstructing.; a hub ol' the 4realen strength with the least` possibleamount ol' friction.

With these ends in view, this invenlion consists in the details ol"construction and eonibirniiion ol' elements hereinafter setforth andlhenspeeiliinlly designated bythe claims.

ln 'order that those skilled in the art to which this inventionappertains nia-y understand how to malte and use the same we willdescribe its construction in detail, rel'errinpr by letter to theaet'oinpanying drawing; forming' a part nl this specification in nhichf*l Figure l, is n. side View ol the hub, a por tion being sectioned so asto clearly show the position oi" the axle and the rolls therein. Fig. 2,a'. section at the line K-X of Fig. l looking;l in the direction oi thearrow, and Fig. 3, :i section al the line af-a looking in the oppositedirection..

ln carrying' outour invention as here enibodied, A represents the hubwhich may be ol any suitable material preferably metal,

'and Within this hub are lorined the cylindrioal recesses B and B', thelatter of larger diameter than the former. .These tp'o recesses areconnected by a tapered bore C. A

D is a series oi rolls located in the recess B and adapted to travelupon the largest diameter of the axle-E, and these rolls are journaledupon the spindles li1 the inner ends of'whieh iit into suitable holesinthe hub while the outer ends are set in the plateA G, the latterbeing'held rigidly in place in any suitable manner hereishown 'as by thescrews H.

l is the usual collar upon the'aXle and J is a Washer of a diameter toextend beyond and engage spindles F at the rearof the hub, said Washerbeing 'fitted between this collar and the plate G.- When the a-Xle is inlace Within the .hub the recess B will be a most entirely inelosed andin order that the rolls may be lubrieatedwe forni a threaded openingfrom the outer diameter of the hub to the recess and elose the sainewith a threaded plug,r or screw K.

',lhe recess B has located therein the rolls .li which are journalcdupon the spindles M, the inner ends ol which are set stationary in.holes formed in the hub While their outer ends are tightly iitted inholes for-ined in the plate N, the latter' partially inclosing therecess but having a hol'e through the center thereof for the passage ofthe smaller di| aineter oi' the axle, and this plate is held rigidlyL inposition in any suitable manner here shoivn bythe screws The outer endof the aide is threaded 'for the reception ot the nut between which andthe plate N is interposed a Washer Q of a diameter to extend .beyond andengage spindles M, and aroundthe outer riin of the hub is secured theband R, or il desired, this may be cast or otherwise formed with thehub.

The recess B has a threaded hole leading thereto which is normally keptClosed b f the threaded plug or screw S so as to iaei itate thelubricating of the rolls L.

" From the above description it will be seen that in an axle having twodiameters and a tapered portion connecting the saine, 'the hub will 'fitupon this axle and the rellsl) travel upon the surface of large diameterwhile the rolls L travel upon that ot' small diameter, andl as'therecesses in which these rolls are journeled are inclosed, oilor otherlubricant placed within these recesses will continually lubrieate theserolls as they travel uponthe axle and all dust and dirt will be excludedtroni the journals. v

By making the axle of two diameters the general effect of a tapered axleis had, thus providing for the greatest strain to -iall upon thethickest portion of the spindle of the' i axle which is essential invehicleuse.

Having thus fully described our invention, what we claim as new anduseful, is-

ln combination with an axle 'and -a hub thereon having a pair ofseparated recesses therein, a series ofrolls in eachreeess, a spin-'dle, for each roll, one end ot each spindle being received in anapertureprovided there for 1n the inner end Walls of said recesses, eachofthe ends ol the hub being' formed sii h mi nmndzii xoooos whivll formsa shouidvi nl Ino 0mm' ends of .said first named romiumudm perforatedplato snugiy in oooh of lmid sovond named round homing against saidshouiders, feci-mv :Umvd to said platos and the hub, thin im md5. oi'said spmdios boing ocoived in tho Iwifointion provided therefor in soipianos, Amid indo hzwiog'viis outer ond threadod und 'having a collar onits inner and, a wasnoi oi' a diameter to oxtond beyond. and oligo thepindles at the 113m of the hub intoiposod imm-oon the plato and tho roarof the hub and said colar of the axle, a second Washer of a diameter toextend bevond and engage the spindles at the iront oif the hub and o nuton the threaded port of the axis to engage the outer foce of the secondwasher.

In testimony whereof, We have hereunto aixod our signatures in thepresence of two subocribing Witnesses.
